Title: Fluid material feeder
Inventor: YOSHIOKA NAOMI
IPC: C23C16/455
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To prevent changes in quality of fluid metallic material, generation of vapor, and reaction product caused by contact with the atmosphere, while the fluid metallic material is carried. SOLUTION: While a migration liquid (F) is fed upstream in a pipe P3 using a pump 23, a fluid material (M) fed from a fluid material container 21 to the pipe P3 is pushed out by the migration liquid (F) and transferred to a vaporizer 1. In this case, a pump or a mass flow controller(MFC) for transferring the fluid material is not required to be set at the pipe 3, so that reaction product caused by contact of the fluid material (M) with atmosphere or a change in quality due to long residence time of the fluid material in a pump as a dead volume can be prevented. In this case, an inert gas can be used rather than the migration liquid (F).
